DISINFECTANT-DISTRIBUIING DEVICE.

Specification of Letters Patent.

Patented Sept. 12, 1911.

Application filed November 17, 1909. Serial No. 528,610.

To all whom it may concern:

Be it known that I, THOMAS E. DUNKLEY, a subject of the King of GreatBritain, and resident of Maumbury Way, in the town of Dorchester, in thecounty of Dorset, in England, have invented certain new and usefulImprovements in Disinfectant-Distributing Devices, of which thefollowing is a specification.

The invention relates to improvements in disinfectant distributingdevices, as described in the following specification and illustrated inthe accompanying drawings that form part of the same.

The invention consists essentially in the novel construction andarrangement of parts, whereby the water in a cistern is charged with therequired quantity of disinfectant by the overflow from a receptaclereceiving its additional supply of water from said cistern through theoperation of a ladling member associated with a float.

The objects of the invention are, to destroy harmful bacteria in cisternwater, to distribute a suitable disinfectant in uniform quantitiesaccordingly as the water supply is replenished, and to devise a simpleand positive acting device which may be made very cheaply and will notget out of order or become choked up and stop the supply of thedisinfectant.

In the drawings, Figure 1 is a perspective view of my device partlybroken away to disclose the interior construction of the disinfectantreceptacle. Fig. 2 is a vertical sectional view of a portion of acistern showing my device attached thereto and in position with thewater at a low level. 3 is a sectional view of a portion of a cisternshowing my device arranged therein and in its raised position,discharging a supply of water into the disinfectant receptacle.

Like numerals of reference indicate cor responding parts in each figure.

Referring to the drawings, 1 is the disinfectant receptacle preferablyformed of thin sheet metal and having an open top.

2 is a vertical partition arranged close to one side of the receptacle 1and extending downwardly from the top to near the bottom thereof, saidpartition dividing said receptacle into the compartments 3 and arespectively.

5 is a spout secured to the outer wall of the compartment 4 and openingslightly below the top of the receptacle 1.

6 are hooks secured to the back of the receptacle 1 and adapted to formsupports for the said receptacle.

7 is a bracket rigidly secured to the front face of the receptacle 1 andprojecting outwardly therefrom and forming the station ary member of ahinged joint.

8 is a float having a bracket 9 secured thereto and pivotally secured tothe hinged portion of the bracket 7.

10 is a trough shaped member rigidly secured to the upper side of thefloat 8 and supported therefrom by the brackets 11. The trough 10 isopen at one end and formed with a V-shaped notch 12 in the bottom sideof said end. The opposite end of said trough is closed in by a plate 13rigidly secured to the upper and outer edges of the sides and bottomedges of the trough, thus forming a ladle shaped receptacle at the outerend of said trough.

In the use of this device, the compart- -ment 3 of the receptacle 1 isfilled with crystals of permanganate of potash or other suit-abledisinfecting material and after being placed in position in the cisternthe said receptacle is filled with water. The float and ladle securedthereto remain in the position shown in Figs. 1 and 2 until the waterrises sufflciently to lift the said float. Before lifting the float,however, the water rises above the level of the upper edge of the plate13 forming a ladle at the end of the trough 10 and as the watercontinues to rise the float is lifted upwardly and swinging upwardlylifts the ladle clear of the surface of the water. The open end of thetrough 10 swings over the edge of the receptacle 1 before it reaches ahorizontal position and the float risin still higher tips the saidtrough upwardly at the outer end allowing the water contained therein todentally into the water. It will thus be seen that as'the supply ofWater in the cistern is replenished the pivotal ladle will discharge asmall quantity of water into the disinfectant receptacle and a uniformquantity of the disinfecting fluid will be distributed throughout thecontents of the cistern.

'A device such as described is very simple and as there are no valves toget out of order the discharge of disinfectant will al- Ways be assured.

What I claim as my invention is 1. In a disinfectant distributingdevice, the combination with a cistern, of a receptacle supported withinsaid cistern and adapted to contain a disinfectant, a float operativelysupported and adapted to rest on the water in said cistern, and a ladlemember secured to said float and having a spout portion adapted toextend over said receptacle to transfer small quantities of Water intosaid receptacle from said cistern on therise of the level of the watertherein to dilute the disinfectant contained within said receptacle andto cause the same to overflow into said cistern' 2. In a disinfectantdistributing device, the combination With a cistern, of a receptaclesupported within said cistern and having its interior divided into twocompartments, said compartments communicating with each other adjacentto the bottom, one of said compartments being adapted to contain adisinfectant, a float pivotally connected to said receptacle, and meansassociated with said float and adapted to ladle Water into one of thecompartments in said receptacle on the rise of the level of the Water insaid cistern.

3. In a disinfectant distributing device,

- the combination with a cistern, of a receptacle supported within saidcistern and having its interior divided into two compartmentscommunicating at the bottom, an overflow spout leading from one of saidcompartments, a float pivotally connected to said receptacle, and aladling member supported from said float and adapted to ladle Water intoone of the compartments of said receptacle on the rise of the level ofthe water in the cistern.

Signed at VVeymouth, in the county of Dorset, England, this 29th day ofOctober, 1909.
